Question

Smallest six digit even number using 1 to 9 only once

Answer 1

Answer:

123456

Step-by-step explanation:

Six Digit number using 1 to 9 digits using each digit only once

so we need six digits

one each at

100000 place

10000 Place

1000 Place

100 Place

10 Place

1 Place

As number should be smallest so 100000 place should be smallest  

hence 1 and next 10000 Place = 2 & 1000 Place = 3  , 100 Place = 4 , & 10 Place = 5 & 1 place = 6 ( 6 is also even number as the requirement was for even number)

1*100000 + 2*10000 + 3*1000 + 4*100 + 5*10  + 6 = 123456

so number = 123456
